If you're searching for an affordable weekend escape in Miami that combines outdoor fun and water activities, this secret $6 waterpark at Larry and Penny Thompson Memorial Park is an absolute gem. Open only on weekends starting June 6th, this spot offers access to an exciting waterslide experience plus the park’s beautiful lake beach area — all for just six dollars per person. Having visited this waterpark myself, I can attest to the vibrant, family-friendly atmosphere and the refreshing feel of the water on hot Miami days. The lakeside setting adds a natural twist to the usual waterpark experience, letting visitors enjoy both thrilling water slides and tranquil beach vibes. Since it’s a lesser-known destination, it rarely feels overcrowded, giving you ample space to relax or have active fun. Another plus is the park’s location at 12451 SW 184th St — it’s easily accessible by car and offers plenty of parking, making a spontaneous weekend outing hassle-free. Plus, the affordable entry fee makes this a great choice for budget-conscious travelers or locals looking for new things to do in Miami without breaking the bank. Beyond the slides, the park has shaded picnic areas perfect for family gatherings or just taking breaks between swims. I also recommend bringing along a picnic or some snacks, as the on-site options are limited, which allows you to customize your own little lakeside feast. Whether you’re a local resident or visiting Miami, adding this waterpark to your summer itinerary is a fantastic way to beat the heat, enjoy some unique water fun, and discover one of Miami’s secret spots where affordable adventure awaits.
